She then tweeted another pic of her son and the new dog, noting, "Mason renamed him Chody"

Brandi has offered up a $10,000 reward for the return of Chica and employed an answering service to handle calls relating to the lost dog. "She is gone still," she told E! News Monday. "We are all devastated."

She's also placed flyers with Chica's picture and contact information in the areas surrounding her Beverly Hills-area home. Unfortunately, however, some locals aren't OK with these efforts.
